Topic: Can I activate the Mario maker 2 NSO bonus when ever i want

I don't really wish to activate the bonus until smm2 actually releases as I would mainly use it just for smm2. The only thing I'm worried about is will I still be able to use the code once it's released or will I have waited too long to activate it?

I firmly believe the code will work once the game is released. Otherwise it's mostly pointless

They always have a email or receipt notification saying how long your code is good until this date. So look there for the timeline to use before it expires.
